It’s carbon dust, which your body is pretty good at dealing with, and in quantities so trivial you probably already inhale more currently than you would using a pencil in an otherwise mostly sterile spaceship (at least sterile compared to earth)
You want a long drawn out answer?
Ok then. Simple fact, our world is naturally dirty, just go outside in spring and you’ll breathe in untold amount of pollen everyday. Yet our lungs cope. How? By excreting mocus and its cilia to carry out foreign material out. However, if an excess amount of foreign material overwhlems the protections the lungs offers, then problems occurs. That of course ignores materials that are toxic, radioactive, or carcinogenic. So unless you are using a pencil made from pure carbon-14… its harmless.
If you wanted clarification or a ELI5, next time just ask instead of being passive agressive.

Plus, inhaling graphite dust since it doesn’t fall doesn’t sound fun.
Plus, graphite dust and electronics are also not a great combination.

Have you broken a pencil tip? I wouldn’t want to breath that in after it goes flying.
Hardly anything is less problematic than graphite. No idea why you think that is an issue.
You’re probably thinking “it’s just carbon, nbd”, but that doesn’t mean it’s good for your lungs:

“Repeated or prolonged inhalation of dusts may cause effects on the lungs. This may result in graphite pneumoconiosis”
I mean water is toxic if you drink too much. The amount of dust of a pencil is negligible… now graphite from pencil production? Thats more concerning.
